SOLE-SEWING MACHINE.

Application filed February 21, 1917. Serial No. 150,190.

To all whom it may concern Be it known that we, JoHN W. GODDARD and ARTHUR E. JERRAM subjects of the King of Great Britain, resldin at Leicester, in the county of Leicester Eng and. have invented certain new'anii useful Improvements in Sole-Sewing Machines; and We do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enable 0t iers skilled in the art to which it appeitains to make and use the same.

The present invention relates to sole sewing machines, and more particulurl to machines of the type having a'rotatalile horn upon which the work is supported, and which carries a looper for placin the thread in the barb of the needle, which atter penetrates the workfrom the side opposite to that side of the work which is on the horn.

An object of the invention is to provide certain improvements in that class of machines of the above kind which act to form a lockstitch. the loop of thread drawn through the Work by the needle being passed around a shuttle which is given a rotary movement preferably c'c'intinuonsly in the same direction. In some of these machines the loop of thread for the needle is supplied in part by the drawing down to the work of a slack loop left upstamling from the previous stitch and in part from the thread supply means (including a takeup at the base of the horn). and the shuttle by drawimn taut the needle loop completes the setting; of the last stitch and draws oil from the needle thread supplya sullicicnt quantity for tho sfitchjthc loop escaping from around the shitt tlc hcing' thcn part1 drawn through the work by tho takcnp. ('ustomarily the shnttlc is moved to rotate about a more or loss horizontal axis which usually runs from front to back of the machine. and usually there is a inorc or less vertical main shaft having: rain or other dcviccs at its lower part to operate the loopcr and takcup. and at its upper cnd a hand wheel for turning. thcmachine by hand. together with an assemblage of'canis (cithcr actually onthc main shaft orupon a cross shaft) for operating variousof the operativc members such as the needle bar. the feed point. the presscr foot. and the shnttlc. An example of this class of machine to which Specification of Letters Patent.

the invention in certain of its nspects more particularly relates is disclosed in the patent to John W. Goddard, No. 1,171 714, dated February 15,1916.,

The chief purpose of the improvements according to t 1e invention is to permit of increase in thespeedof operation ,of such machines and of reduction of the time occupied in inevitable stoppages in theoperation ofthe machine, with a View tojncreasing the output capacity of such machines,

One object of the invention-- is to facilitate the placing of work upon andthe withdrawal of the same from the work supporting horn of sole sewing machines. lVith this object in view, one feature of the invention consists of, in a sole sewing machine, a construction of the looper actuating mechanism and the hornsuch that the tip of the latter can be moved laterally outof and into sewing position without producing such disconnection of the actuating mechanism as permits variation of the timing of the looper.

Conveniently. there is provided a device controlling the position of the horn. which device may be coupled to the resser foot, and connectionsbetweenthe device and the machine starting treadlc such as to prevent starting of the marhine until the horn is either fully out of or in sewing position.

Anothcr object of the invention is to facilitatc access tothc bobbin and to the 0 mmtivc mechanism in the neighborhood thereof in lockstitch solesevi'ing machines which have a deflecting: element which acts to deflect or spread the 'loop ,toeeuahlc it more -readi'lvto be takenbyizhe shuttle (see for example the machine" of Patent No. 1,171.714)

am according to anotllel" featurc of the invention this is cli'cctcd by mounting the dellcctin; clcmcnt upon the bobbin cover so as Ara-Ma ling to this feature of the invention the shuttle is mounted for rotary movement in a memher which reciprocates transversely of the plane of the aforesaid movement. 1111i the shuttle has its rotary mnvmnent impartetl to it hy drivers adapted in more into and out of engagement with the shuttle aiul guhlell in a member whirl; is given a mtary uirwemunt to more. the shuttle. hut in hehl against movement transversely of the saiil plane. lrei'erahly the memher movie in the vicinity of stationary 'ini means uhirh art to eil'eetthe nth-antic and withllltlWili of the ilrivfs.

further olajeetot the. invention is to proviile improved work t'eetl mcvhanisni l'ol' sole sewing machines. ('ust'zi-marily in sole. sewing machines the presser i'oot avts as a support for the tee l pnint. aral when the presser foot is llfttbil in preparation for ilu: feed mmemenl, the Fetal point is in man sequente slightly littexl. .\t this time. (la-1efore. not only is work releasell by the pressei foot, hut the feed point to some extent releases its hohl upon the Work and the :u;'-- cnrnt'y (ii feed alnl of positioning! of the work may be materiall; afi'eete l. eapm-iall when the work is hehl mueh ine ein il to the horizontal. Again the hat that the let-ll point in such machines enters the work in air iiulineil direction. and drags ililt'it over the wort: on the return stl'ohe. has been t'ounrl to have disadvantages whit-h t. is an ohjeet ot' the. present. invention to m'ereome.

With these further objects in View. one feature of the present invention consists of. in a sole sewing machine, the eomhination of a needle har actuated to move towawl and from the work in the-same path. work clamping means (for instance a 00- fling presser foot and horn) and a fe l memher (lawn ally movable to feed the work) whieh moves towaril the work along a pathway suhstan tially perpendicular to the same, and is operated luring sewing: to he in etl'eetive eontrol of the Work at all sueh times as the elainping means veases to have sla'h voutiol.

In some of the views eertain parts ham hean omitted for the sake of simplicity. Like rofi'ireuee. charm-tiers indicate parts in all the figures.

ln the ha: of the machine and running I'rmn hatch to front is a ilriying shaft. 1 (Fig. i!) vonnurttul h a clutch (not shown) at, the rear of the mmrhine to the source of power Hlh'l wart-yin near its lorwarll enel a hovel gear wheel 11 meshing with a similar gear wheel 33 m: the hottoni (illll of a. more or less upright shaft 1 running up inside the stand arcl 5 of th." inarhiin; and projecting from the same at thctop of the machine as shown in Fig. I}.

This shaft. rarries toward its lower end a harm-l meml'vr U in whivh are formed three. ram tin-wits T. H. 1). one for operating the threacl liu'fh' (to he he :einal'ter deserihml). aml the others for .ipeiuting the ievurs ol' the taheup derive. whieh will he il serihmi lwlouz Adjacent to this member if a lieu-l gear wheel hi mnshiz with a.

I lb .-nnllar .r whuei 11 o] the mechanism for like llll) driving the whirl in the horn. At its up permost extremity the shaft beans :1 hand wheel 12 by which the machine can be slowly turned by hand and immediately beneath this hand wheel and within the stamiard the shaft carries a bevel gear wheel 13 for operating the main shaft on the ma chine head, and an eccentric 14: for recipro- .cating the shuttle carrier axially, and is in verticahtnbular shaft having earings in the base of thediorn, and provided at the lower end with a bevel gear Wheel 17 (Fig. 2) meshing with a similar gear wheel 18 on one end of a short horizontal shaft 19, on the other end of which is the gear wheel 11 above referred to as meshing with a corresponding bevel gear wheel 10 on the upright shaft 4 in'the machine standard.

The horn is mounted to be free to rotatc on a ball race carried in a horn support 2H having depending lugs 21 at opposilc sides in which are hearings for short coaxial shafts 22 pro'ectin from opposite sides of the machine rame elow the horn and running from side to"side of the machine. The

horn can thus be swung forwardly toward the operator out of its normal upright posi- '.tion. iving increased clearance between the tip of the horn and the various dcviccs of the head. such as tho press'cr foot, t'ccd point and needle, and facilitating the rapid withdrawal of the work from and placing of work upon the born.

The axis of the shafts about which the horn swings is so disposed as to be tangential to 'the bevel gear wlu-cls IT and In. on the tubular shaft and the horizontal driving shaft 19 respectively. at lbc point 23 where thcir bascs mesh. and a stop ill on the machine frame is adapted to form an abutment for the horn sup wort when the lattcr is swung fully out. his arrangement sc urcs that the horn may bc frcc to swing and the ear wheel 17 may be frec to swing awrom the gear whccl 18 without at the some time these gcar \vhccls becoming complctcly unmcshcdaml any risk of change of t iming of thc whirl arising.

.\[ountcd to be movable horizontally from back to front of the machine is a locking bolt 25 having a wedge shaped forward portion 26 adapted to engage ovcr a wcdgc shaped projection 27 on one side of the horn support when the horn is upright, and it look it in position, or to en age beneath the projection when the horn ms been swung out of )osition and so hold it in that. position. he bolt 25 is engaged by one end of a lever 28 by which it is moved horizontally to and fro to effect locking and unlocking of the horn. This lever is pivoted at 29 inside the standard of the machine, and carries at its other end a roll 30 engaging a cam Pack 31 formed at one end of an arm 32 of a bell crank lever pivoted at 33 on the standard the other end of the second arm of which is pivotally connected at H to the upper end of an o crating rod 35 hereinafter referred to. he cam track 31 is also engaged by a roll ace mounted on one arm of another bell-crank lever 370 pivoted on the standard at 380 the other arm of which is connected, by a rod 391), extending up the standard to the head of the machine, to the presser foot lifting lever. The arrangement of the bell-crank levers and the lever 28 con ncctcd to the bolt an as well as the form of the cam track 31 is such that if the arm 32 carrying the cam track is swung under the influence of the operating rod 35 in one direction the prcsserfoot is first raised and as tho a rm swings furtbcr the locking bolt is withdrawn and the horn can be swung out of position. (onverscly upon movement of the arm in the other direction the bolt first advanced to lock the horn in the in or out position as the case may lie and then the prcsscr foot is allowed to descend. There is provided in conjunction with the operating rod 3.3 mechanism which aims at insuring that the clutch shall not be thrown in except when the prcsser foot is down (and the horn consequently locked in the in or out positions) and that danger of the machine being started with the horn in an intcrmediatc position. involving possible damage to the needle and associated parts. shall bc avoided.

The clutch-opcrating lever 36 extends toward the front of the machine and has projccting from one sidc of it a horizontal pin Ili with a V-notch cut in its upper sidc. livotcd on the same shaft 38 as the clutchopclnting' lcvcr 36 is a second lcvcr 3S1 lying alongside the latter and having projecting from it adjaccnt to the clutch-omrating lcvcr a pin it) similar to that already referred to but situated a little fa rthcr from the shaft 38 upon which the lovers are mounted. The lcvcr ll!) isnormally held up by a spring 41 against a stop 42 on the nmchinc lmsc and is pivotally conncctcd at 43 to thc lower cud of the operating rod 35. A trcadlc 4-1- for opcrzlfing both thc clutch and the pres-scifoot and horn lock is also mounted upon the shaft 38 and is normally urgcd upward by a spring 45 connected at one cud to the lcvcr and at the other cud to thc machine frame. in the neighborhood of the horizontal pins 37. t0 the treadle H has an upstanding hral'lcet 4-6 from which a short horizontal shaft 47 projects over the pins referred to. .\n arm 48 is mounted on this shaft so as: to he capahle ol' swinging over either of the pins 3T. 40 and engaging in the V-notch of one or other of them when the treadle it is depressed. n the end of the treadle on which the operator places his foot is an upstanding arch or stirrup 41) from which depends a plate fillwhich the operator can thrust forward hy for 'ard motion of his foot on the treadie and a rod 51 is disposed hetween and connects this plate with the arm rH'so that the ope 'ator can swing the latter into position over the notch in the pin 37 on the clutclr-operating lever 36. A

spring-pressed plunger fil honsed in the up,

standing hracket lt'i hears on the opposite side of the arm 43 and acts normally to maintain the arm in position over the notch in the pin 40 on the lever 39.

When once the presser toot has been raised and the horn swung out of position the pivotal arm 48 on the treadle 44 will remain in engagement with the notched pin 40 on the lever 39 until such time. when on the treadle it rising the lever 39 is urged by its spring 41 against the stop 42 and there arrested when further upward movement of the treadle will bring the arm 48 out. of the notch in the pin in and leave it free (the presser foot heing nowin normal depressed position and the horn locked in the in or out position) to he swung over to engage the pin 37 on the clutch-operating lever ll: and allow the clutch to he thrown in.

in a chamher formed in the frame of the machine hclow the horn Support are the thrad-loeking and thread take-up devices. The thread-locking device comprises a lever 52!. pivoted on the frame at 5+. one arm of which is hollowed to receive a springpressed plunger which when the lever is swung in one direction is hrought against a surface 36 on a lixed arm 5T projecting from the frame. lhe surface 5G and the plunger 55 are grooved transversely to the direction of the thread. which passes therein-tween. so as to atford a good grip on the thread. The other arm of the lever 53 is connected to the frame of the machine by a light spring in which normally urges the plunger 55 against the surface at). The plunger heing yieldingly forced against the surface. variation in thread suhstance can take place without any tendency to cut or crash the thread unduly during the locking. The other arm of the lever 53 is also adapted to he engaged by one arm of a tappet lever fitl pivoted on the frame the end of the other arm of which is formed as a cylindrical pin (it) engaging and capable of moving longitudinally in a ball (ll engaged in the corresponding earn track 9 of the barrel member 6 on the upright driving shaft l in the standard of the ma chine. ln cross section the cam track is circular and the hall is thus held tirintv in the track. there heing a cutaway portion (conforming to the cam track) a little wider, than the diameter of the pin on thr'nigh which the latterprojects.

The tixed arm 5? which carries one of the thread-engaging surfaces also carries a pallev around which the thread passes as it leaves the locking device. From this palle the thread passes upward over a pulley 62 on the upper of two take-np levers 63. (it and thence down and around a pulley US on .the lower of the take-up levers the thread then passing vertically upward into the tubular shaft in the base of the horn. The take-up levers are each pivoted to the frame of the machine and their ends remote from those carrying the pulleys engage in halls in the cam tracks 7. H on the barrel member (3 in the same way as the operating lever for the lock already described. The cam tracks are so formed thatthe take-up levers have a scissor-like movement hoth moving together or apart at the same time.

The shuttle (it; (Fi l) is mounted to rotate on an axis running from the front to the hack of the machine and slightly inclined to the horizontal so that the hody portion of the shuttle is clear of the needle har when the heak ()7 of the shuttle is taking the loop of thread. shuttle-carrying casing (3H is provided which is pinned to one end of a shaft- 199 parallel to but ahove the axis of rotation of the shuttle. The shaft on has hearings in the head of the machine and is free to move longitudinally in its hearings. its other end is connected h an eccentric adjusting pin TU (Fig. 3} to an eccentric arm T1 the strap T2 of which eneircles the eccentric 14 (already referred to) on the uprightshaft r in the maehine standard. The casing and theshnttle ear-- ried by it are hy this mechanism reciprt rated axially intoand out of the path of the needle once in every revolution of the upright shaft 4. The asing has two curved plates 73. T4 (Fig. 4) removahly mounted on it. which together form a part circular llange which projects into a peripheral recess in the shuttle. and thus forms the support and l *aring surface for the shuttle in its rotary and axial movements.

To rotate the shuttle the shaft l5. hereinhefore referred to. is provided which is coaxial with the axis of rotation of the shuttle. The driving connection hetween the shaft 15 and the upright shaft 4- causes the shaft 15 to perform two complete revolutions for every revolution of the shaft 4., and thus as will he hereinafter explained. for every complete cycle of operations of the needle and associated memhers. linned to the forward end of the shaft 15 is a ey- 1,171,714, except lindrical hloek 76 having two diametrically opposite grooves cut on its outside face parallel to the axis of the shaft. In each groove is mounted a shuttle driver 77 the forward end of which can be reeiprocated into and out of a corresponding recess in the rear face of the'shuttle the reciprocation of the drivers being effected on the rotation of the block 76 by the coaction of a pin 78 projecting from each driver with the corresponding one of two cam tracks 79, 80 formed on the inside walls'ot a fixed cup 81. within which the block 76 rotates.

The shuttle-carrying casing 68 is pro vided with a hinged cover 82 mounted and actuated in the same manner as the hohhin holding arm disclosed in Patent No. that the axis of the hinge is horizontal so that the cover swings 't'or- \vardly and upwardly on opening. A loop deflector of the kind disclosed in atent No.

1.171.714 is mounted on this cover so that it is swung out of the way when the cover is swung open. The deflector consists of a vertically disposed lever 83 (Fig. 5) pivoted iiv a pin H4 mounted in the shuttle cover so as to swing on an axis running from side to side of the machine and so that the lower end of the lever can swing across the path of the needle toward the shuttle when its upper end is engaged hy a cam piece H5 on the needle har 86, there heing a spring 87 coiled ahout the pivot with which the ever F43 swings which acts normally to keep the lower end of the levento that side oi the path of the needle remote from the shuttle.

The needle har H6 is mounted to slide in top and bottom hearings 88, 81) in the front of the machine head and hetwecn these hearings has a hlock 90 attached to it, which l l()(3l( is in engagement with a vertical guideway 91 on the head and holds the needle har against rotation. l ivotod to this block is, one end of a link 92 the other end of which is pivotally connected to one arm 925 of a hcllarra'nk lcverliivoted on a crank 94 on'tho main sha'l'tonlheinachine head. 'lho other arm 95 jsoe alsofil ig. of the hellcrank lever carries a roll 00 engaging a cam track 07' formed in the side of a fixed cam disk 98 disposed coaxially withlhc main shaft 0!) on the machine head. The link 92, hell-crank lever 93 -95,-cran'k 94 and cam track 07 are so formed and arranged that the needle har is operated in the. manner indicated llld'ljt spiazitication oi' Letters lalcut No. 1,120,201.

l ast to the mainshaft the head is a. am disk 100 (Fig.3) lltl ii'lllgu'l lll the purposes hereinafter dcscli'ihcd formed on one face of it two cam tracks 101. ing a single cam track 10: on the other face. The prcsser l'oot l0l (Fig. 5) is pivotallv mounted at the holtoni ol' the prcsser l'ool bar 105 and is urged normally against a stop 109. and hav-' 106 by a spring-pressed plunger 107 mounted in the prcsser foot and hearing on the presser toot har, the arrangement heing such that when the presscr foot is clamping the work this plunger has heen thrust hack and the presser foot is in direct and unyielding contact with the presser l'oot har whereas the spring-pressed plunger heroines effective during the feeding movements to swing the work-engaging surface of the .presser l'oot down and maintain it under light spring pressure in the channel or groove, if any, along which the line of stitching is to he laid. The presser foot har 105 is provided with a longitudinal (i. c. vertical) guide or recess adapted to receive the feed point har 1.08 also Fig. (3) and guide it in its vert1cal movements while allowing a limited movement of the feed point bar 108 laterally away from the presser foot har 105. The tops of the presser toot bar 105 and of the feed point har 108 are respectively pivoted at 109, 11 to the two hottom corners of a vertically disposed triangular plate 111 the upper corner 112 of which is pivotally connected h a link' 113 to one arm 114 of a hell-crank lever pivoted at 115 to the machine head the other arm 116 of which carries a roll 117 (Fig. 3) engaging the cam track 103 in the. cam disk 100. The atrangement is such that the link 113 in the alternate raising and lowering of the presser foot and feed point reciprooates the. triangular plate 111 the point of connection of one of the hars e. presser foot har 105 or feed point har 108) to the plate lll and then the other forming the fulcrum about which the plate moves, the point of connection ahout which the plate is swung at anyparticular time hcing stationary by virtue of the fact that the har which carries it is at that time l'iearing on the work. In other words while the plate 111 is swinging to raise the presser foot the point of connection [10 ot' the feed point har the feed point at, that time engaging the. work) to the plate 111 forms the fulcrum of the. plate and vice versa.

The feed point liar MIR is swung about its point of connection to the triangular plate 111 to give the necessary feeding motion to.tho feed point by a bell-crank lever pivoted on the machine head and hearing on one arm 122 a roll which engages the cam track 101 on the cam disk 101) and on the other arm 123 a pin 124 connects that arm to the lower end of the feed point lllll' ll t Both the feed point bar 108 and the arm 123 are slotted so that the pin 124 may he moved along the slots to adjust the feed stroke the pin being provided with a clamping nut 12:) to secure it in adjusted position in the slots.

The link 113 which operates the triangular plate 111 is provided with a projecting tail 126 against which the end of a lever 12? pivoted on the machine head at 12 and rum ning horizontally from front to hack thereof can engage to lift the lilOSstI' foot from the work. this presser foot lil'ting icver heing, as already referred to. connected to the o 'ierating rod 391) which extends up the standard of the machine.

To lock the presser fool in position a lrellcrank lever is mounted on one side of the machine head one arm 129 of which lover has a wedgwshaped end portion adapted to he forced against the prrss r foot bar to lock it hv a spring-pressed plunger 132 which is housed. in the machine head and urges the wedge surface on the arm 129 normally into conta t with the side of the presser foot lHll 11 5. To unlock the presser foot bar at the required times a tappet lever 13H is provided hearing on the other arm 131 of the l ell-crank lever and operated hy the cam track ll i on the ram disk 14)!) to remore the wedge suri'ai-e out of rontact with the presser l'ooi ha r.

The operation of the machine i as follows Assuming the horn 1rio have liven swung in its outward position the 'opcrator lirsi places the work upon 1hr horn and then depresses the trcadlc l-l thus raising the prosser foot and drawing hack the locking holt 525. The horn is now free to he moved into the upright position and the operator having so moved it he releases thc treadle allowing the presser foot lo fall and the holt 1'5 to advance to lock the horn in position. The

treadle having risen suliicieutly to clca r the arm 1H from the nolrhed pm -I-() on tlit lever 39 the operator thrusts his foot. against the plate and tlltl'\l) swing the arm -lN ovcr opt-ration to lock the thread and then, the

It willlhe convenient lo'i-oninn-m-e the con-- sideration of the sewing operation at the moment when the needle is about to Inovrdown toward the work from its highest point (see curve i\ ii Fig. T). At this time the shuttle (so has ver v nearly completed its axial movenn-nt in the direction toward the path of the needle (see curve C, D lti ig.

T) and the beak UT of the shuttle is almost in the loop-rccriving position. At this time the presscr foot support [(15 is held raised (see curvil l, Fig. 7) in anticipation of the feed movement of the work now ahout to connuonce while the loop deflector Zl (see curve (i. ll. Fig. 7) is ill. its inmost position to hear on the loop lu'lween the. needle and the surface oi the work.

.\i the moment the needle. commences to descend the heat UT of the shuttle has penetrated well into the loop and the feed point (see curve I M.

At this time moreover the loop duller-tor 83 which has hcen gradually moving away from the ncedle path (see curve (i. ii) and out of loopalellccting position completes this nlovunu-ui, Shorll hol'orc. the bottom of the rc is la'hind lln lu'llh (\T reaches; in the rotation oi" the huttle. its highest point (the. movements ol the hoitom of the ['(ttss being shown ll! the curve 'l. 1. Fig. T) the feed movement oi' the feed point is rompleted (soc i'HIVt 1.. M) and almost immediately afterward the prc scr l'oot support 105 (see curvil). l commences to descend toward the work. Your .-'ll()l'tl after the hottoln of the IW'ws referred to has passed its highest point (see rurvo T, U) the thread lork 5.1 so (.ii-e curvv il b) once more comes into .pl'csscr l'ooi having come. fully down upon the work (we curvo E, F), the feed point eonmwlu'es to lift away from the work (see eurvc X Y, Fig. T) and simultaneously to rel urn horizi'mtallv to startingposition (see curve L, M) at) that in efiect it commences to eave the work in an inclined direction.

The bottoni of the recess behind the shuttle beak having now traveled well past its highest point (see curve '1, U) the take-up levers commenre to move away fromearh other to draw the loop oil' the shuttle and toward the work (see curves N, and 1, Q). Just before the needle penetrates the work (see curve A, B). as the result otyits eontinued downward moil'enient the locking device 129, 132 for the preslser fiot support (see curve \V, V, Fig. T) onies into operation to lock the same in its lowermost position in contact with the work. Shortly atteiwverd, having ronipleted its horizontal return movement toward the starting position, the feed point begins to (lPSf'GIltl vertically (see curve X, Y) toward and into engagement with the work which movement it completes at about the time when the needle (see curve A, ll) leaves the work on the underside to penetrate into the horn and when the shuttle has completed about three-quarters of its rearward axial movement (see curve D) away from the path of the needle. At this time the shuttle has nearly completed a revolution (see curve T, U) and the take-up levers (see curves N, and I, Q) have come to a stop at their widest separation having taken up all but a small loop of thread which remains upstanding above the work.

Shortly after the bottom of the rrress behind the beak (see curve .T, U) has once more passed its highest point (the shuttle being then in the rourse of gradually advaneing axially toward the needle path as shown by rnrve D) the needle. which has for some time been stationary (see curve A, B) in its lowest position to allow of the placing of the thread in its barb by the. looper, commenres to rise drawing up a. loop of thread one leg of which is supplied from the take-up levers which now cornmenro their movement of relative approatth (see r-urves N, U and I, Q) and the other leg of \vhieh is supplied by the upstanding loop in the last stilt-h \\.lll('.l| as the needle rises is gradually drawn down to the surt'aee ol' the work. As the needle in its upward movement leaves the work the presseir bar support no is illlltfl'h't'll (see curve V, V) and as the needle completes its upward movement the presser i'oot romnienres to lift (see curve I), i in anti ipation of the next, t'eed movement and the loop defier'tor 83 begins to swing toward the loop (see rurve (i, ll) to deliert it in a. direrlion to'aid the entry of the beak T which is now onre again nearly in loiui-reveiving position.
